Whole Spectrum Invisibility

There has been quite a bit of
interest and actual effort aimed at producing an invisibility cloak.I have never really been interested but this
work has now shown us that we may be able to develop a practical device.All of a sudden cloaking a craft is a real possibility
even if it is ultimately not important.

Everyone jumps at the idea of
military cloaking, but the range one would actually need is just way to high
for large craft.Yet cloaking an
individual is worthwhile and this sounds like it could.Recall that the UFO phenomena and related
operatives have constantly demonstrated effective cloaking.

It suddenly may turn out to not
be that particularly difficult to pull off.

Undergraduate opens invisibility cloaking to the whole spectrum

Tuesday, August 9, 2011

A light trajectory is shown against the distribution of the εσ values.
The light ray enters the device, completes a loop, bounces off the mirror twice
and leaves the cloak with its original direction restored (A). Panel (B) gives
a closer view of the vicinity of the inner branch of the cloak. Objects placed
within the white region are invisible.

An undergraduate student has overcome a major hurdle in the development
of invisibility cloaks by adding an optical device into their design that not
only remains invisible itself, but also has the ability to slow down light.

The optical device, known as an 'invisible sphere', would slow down all of the
light that approaches a potential cloak, meaning that the light rays would not
need to be accelerated around the cloaked objects at great speeds ― a
requirement that has limited invisibility cloaks to work only in a specified
region of the visible spectrum.

This new research, published today, Tuesday 9 August, in the Institute of
Physics and German Physical Society's New Journal of Physics, could open up the
possibility for a potential invisibility cloak wearer to move around amongst
ever-changing backgrounds of a variety of colours.

Under the guidance of Professor Ulf Leonhardt, Janos Perczel, originating from
Hungary and reading Logic, Philosophy of Science and Physics at the University
of St Andrews, acknowledged the huge potential of the invisible sphere and was
able to fine-tune it so that it was a suitable background for cloaking.

The usual approach to designing an invisibility cloak works on the basis of
bending light ― using highly specific materials ― around an object that you
wish to conceal, thereby preventing the light from hitting the object and
revealing its presence to the eye of the observer.

When the light is bent, it engulfs the object, much like water covering a rock
sitting in a river bed, and carries on its path making it seem as if nothing is
there.

Light, however, can only be accelerated to a speed faster than it would travel
in space under certain conditions, and this restricts invisibility cloaks to
work in a limited part of the spectrum ― essentially just one colour.

This would be ideal if somebody was planning to stand still in camouflage;
however, the moment that they start to move the scenery will begin to distort,
revealing the person under the cloak.

By slowing all of the light down with an invisible sphere, it does not need to
be accelerated to such high speeds and can therefore work in all parts of the
spectrum.

Perczel said, "I started to work on the problem of superluminal
propagation as Professor Leonhardt's summer student with an EPSRC grant. Once
the idea was present, I worked for over eight months to overcome the technical
barriers and to make the proposal practicable."

An Institute of Physics spokesperson said, "This new development opens up
further possibilities for the design of a practical invisibility cloak ― overcoming
the problem of light speed that other advances have struggled to address and,
very impressively, this significant advance was achieved by an undergraduate
student."

About Me

Apr 2017 - 4.1 Mil Pg Views, March 2013 - Posted my paper introducing CLOUD COSMOLOGY & NEUTRAL NEUTRINO rigorously described as the SPACE TIME PENDULUM, September 2010 I am pleased to report that my essay titled A NEW METRIC WITH APPLICATIONS TO PHYSICS AND SOLVING CERTAIN HIGHER ORDERED DIFFERENTIAL EQUATIONS' has been published in Physics Essays(AIP) and appeared in their June 2010 quarterly. 40 years ago I took an honors degree in applied mathematics from the University of Waterloo. My interest was Relativity and my last year there saw me complete a 900 level course under Hanno Rund on his work in relativity,as well as differential geometry(pure math) and of course analysis. I continued researching new ideas and knowledge since that time and I have prepared a book for publication titled Paradigms Shift&. I maintain my blog as a day book and research tool to retain data and record impressions and interpretations on material read. Do join my blog and receive Four items of interest daily Monday through Saturday.
